Innovative, ecofriendly rigid foam production from pineapple field leftovers

A team of researchers from Thailand, Malaysia and Singapore has successfully harnessed pineapple waste materials from agriculture to create biodegradable rigid composite foams. The foam's base was formulated using starch extracted from pineapple stems, known for their high amylose content, while the filling material was derived from non-fibrous cellulosic components found in pineapple leaves.
